We need to subtract by adding up: [tex]63-28=?[/tex] we get 35

Step-by-step explanation:

We need to subtract by adding up: [tex]63-28=?[/tex]

We will make a number line from 28 till 63 and then jump intervals to reach 63.

We will add those intervals to get the result. That result will be the subtraction of [tex]63-28=?[/tex]

[tex]28+2=30\\30+10=40\\40+10=50\\50+10+3=63[/tex]

So, we will add up: 2+10+10+10+3 = 35

So, [tex]63-28=35[/tex]
